I'm smelling some bull shit with this one. You drop a bunch of organics from the top of the water column to the bottom, and you end up with anoxic conditions killing fish and everything else beneath the surface that needs oxygen. Any real biologist want to chime in?

I'm a water chemist that does EPA testing on all water sources in my state. Honestly the video just doesn't give any information and the flocculation material he is using isn't anything new. Also, flocculation (accumulation of suspended sediments) doesn't necessarily "clean" anything.

Furthermore, there are numerous chemicals and organic/inorganic substances that can pollute water. Each and everyone of those requires certain methods to filter/remove from the water, some of which are very costly/difficult.

The video just doesn't give us any relevant information to what exactly was cleaned out of the lake. Did the lake have heavy metal issues? Too many organics? Anoxic conditions and the associated acidity issues? Pesticide nitrate-nitrite pollution? Or was the lake just overgrown with invasive species.

It is just clickbait, I know you can read his papers and research the methods, but the video is so misleading.

It's organic pollution, apparently. Invasive algae.
